Research Interests

I am the Co-Director of the Transportation Technology and People Lab. TTP is a group of multidisciplinary faculty members, researchers, and students evaluating new technologies and applying avanced modeling and data analysis techniques. More details can be found in the TTP lab webpage.

My research focuses on enhancing system efficiency via the development of novel mathematical models based on application of large scale optimization, machine learning, data mining, and system simulation tools. The primary innovation of my work is in the representation of network uncertainty, robustness, user behavior, and complex system interaction in civil infrastructure networks which together permit a long-term comprehensive analysis. A significant portion of my work deals with mitigating the impact of uncertainty in transportation models. Some of the research topics in which I am interested in working are listed below.
